Johannes Blom, a young sailor, returns to his home port after seven years at sea. He is eager to see Sally, the girl he has been thinking of while away, and finds that she is completely despondent. Seven years earlier, obstreperous Alexander Blom brought his mistress Sally to live with him, his wife Alice, son Johannes, and crew aboard the salvage boat he captained. Amidst all the tensions on the small boat, Johannes and Sally fall in love with each other.
